Iga Swiatek became the ninth woman to win a third major title before her 22nd birthday when she lifted the US Open in September

Iga Swiatek, the world number one, was defeated in the semi-finals of the United Cup.

The third-ranked woman in the world needed just 71 minutes to win her match.

She's one of the best players in the world so you have to be at your best to win.

I am not surprised because I know what she can do. I was surprised I couldn't step up to her game.

The Australian Open is just two weeks away, and the loss is a blow to Swiatek.

She claimed six titles in a row, including the French Open, before winning the US Open in New York.

In Friday's second singles rubber, the United States took a 2-0 lead and were on the verge of a spot in the final.

The man said he had been inspired by the performance of the other team.

He believes he is playing some of the best tennis of his life.

I needed to come out and put on a show for you guys after seeingJess.

The final two singles matches are on Saturday. If needed, a mixed doubles rubber would be played.

Greece and Italy will play in the second semi- final.
